摘要：

The electronic energy bands of PtSn2 are calculated using composite wave variational version of the APW method. The results show a narrowing of d-band which indicates a weaker d-d overlap interaction between Pt atoms. A comparative study of this band structure result with that of PtAl2 and Pt provide interesting information about d-d interaction as a function of primary interatomic distance. From the band structure results, density of states, joint density of states, epsilon-2(omega) spectra and the Fermi surfaces are calculated and interpreted.
